"What is everyone’s favourite side feature?"

I remember really liking the Pokémon contests in omega ruby and alpha sapphire however I don’t see them talked about much nor any other side feature? So that got me wondering what everyone else’s favourite side feature is? (When I say side feature I mean any feature that isn’t the main focus of the game or a major part).View Poll via /r/pokemon https://ift.tt/3bQRD5w
